1 Claim. 1

This invention relates to a nose filter and has for its primary objectto exclude dust and dirt from entering the nostrils of the user.

Another object is to support an inhalant possessing medicinal propertiesin a proper position within the nostrils of the user so that with eachinhalation, a treatment of the nasal tissues may be affected.

A further object is to facilitate the change of the inhalant at thedesire of the user.

Among its features my invention embodies a pair of hollow frusto-conicalnostril inserts, a yielding bridge piece connecting the lower ends ofthe inserts to removably hold the inserts in the nostrils of the user,and means for supporting interchangeable filters in the inserts.

Other features include means for sustaining a suitable inhalant withineach insert so that with each breath th user receives a treatment.

In the drawings:

Figure 1 is a view showing my improved nose filter in use,

Figure 2 is a side view of a nose filter embodying features of thisinvention,

Figur 3 is a bottom plan view of Figure 2,

Figure 4 is an enlarged longitudinal sectional view through the capclosing the upper end of the nostril inserts, and

Figure 5 is a fragmentary enlarged sectional view through one of thenostril inserts of this improved nose filter.

Referring to the drawings in detail, my improved nose filter designatedgenerally lfl comprises a pair of nostril inserts ll each of which isformed as a hollow frusto-conical body having a perforated bottom wall12 which is inset from its lower end, and. an inwardly extending annularflange I3 which is inset a short distance from the upper end of thebody. The body is formed adjacent its upper and lower ends with internalscrew threads l4 and I5 respectively.

Seated against the underside of the perforated bottom I2 is a filter I 6which may take the form of a woven or knitted cloth or fabric, and thisfilter is held in place by a retainer designated generally I! comprisinga ring shaped externally screw threaded body l8 across which extends atransverse bar l9. As illustrated in Figure 5 the retainer I1 isscrewed. into the body against the underside of the filter [6 in orderto hold the filter firmly in place.

A cap designated generally 20 is adapted to close the upper open end ofthe body of the insert II and comprises a hollow frusto-conical body 2|having a perforated bottom wall 22 car y g X.-

ternal screw threads 23 at its periphery for engagement with the threadsI5 previously referred to. The convergent ends of the side wall of thecap l8 ar inturned as at 24 to form an inhaling opening 25 through whichair entering the filter is taken into the nostril.

A filter 26 of gauze of light woven or knitted fabric is adapted to beseated upon the upper face of the inturned flange l3 and clamped inplace thereon by contact with the under side of the bottom wall 22 ofthe cap 20 when the latter is in place in the device.

In order to support an inhalant or medication within the nose filter Iprovide a foraminous cone 2! having an outturned flange 28 at its largerend which is adapted to rest on the flange I3 beneath the filter 26 soas to hold the cone 27 in inverted position within the device. Anysuitable medication may be suspended in the cone 2! by the simpleexpedient of introducing it into the upper open end of the cone beforethe cap 20 is attached in place and before the filter 26 is placedthereover. Obviously a small ball of cotton may be saturated with aliquid inhalant and dropped into the cone 21 so that air entering thenose filter and passing to the nostrils will become laden with thevapors of the inhalant.

By the simple expedient of joining the nostril inserts by a bridge piece29 preferably of a yielding material it is obvious that the device maybe made to grip the nostrils with sulficient pressure to retain it inplace.

I claim:

A nose filter and medication holder comprising a pair of hollowfrusto-conical nostril inserts, a yielding bridge piece connecting thelower ends of the inserts removably to hold the inserts in the nostrilsof the user, the bottom wall of each insert being perforated and meansto hold a filter pad against each perforated wall, an invertedforaminous cone supported adjacent th upper end of each insert to forman inhalant sustaining cup and means to retain each foraminous cone inplace in its respective insert.
